Outlook On The Web Signature Line Disappearing

Two days ago my signature line disappeared from my emails, randomly. I had not adjusted anything within settings and confirmed that my signature is still showing in settings, but it randomly stops showing up and even when I try to manually "insert signature" it just shows up as blank. I have removed it and pasted it in again, and sometimes it will show up for an email or two, but eventually disappears again. I have confirmed the boxes are checked for signature to automatically be included in new emails and replies.

Again, even when I try to manually insert it it shows up as blank. I have to copy and paste it in order to use it.

**When issued first occurred:**4/20/2021
